While uPVC profile bars possess many essential features for window manufacturing, they often lack the necessary stiffness and stability. Fortunately, the incorporation of steel reinforcement has proven to be an effective solution.
Before the welding process, a reinforcement profile is inserted into the inner chamber of each vinyl profile. This steel reinforcement significantly enhances the product's performance, offsetting the impact of temperature changes and preventing deformation in the shape of windows and doors.
Reinforcement profiles are typically crafted from steel and are tailored to fit the design of the inner chamber of the PVC profiles.
Screwdrivers and screw centers are employed to affix the reinforcement profiles by securely fastening them to the uPVC profiles.
